I have had similar problems with Thai citizens at our guest house asking them to put plastic bottles , food waste , cardboard and glass bottles into separate bins . Mostly they take no notice young and old and look at you in great surprise as you ask them . Most foreigners comply , but not all .
Yes , most Thai guests never turn off the lights , fans and air conditioners when they go out . They were mostly coming from Agoda . I put the prices up with Agoda to discourage the Thai business . Oh yes , they park in a way that you wonder what is running through there brain .
